Unexplained sounds Pacific

National Oceanic and Atmospheric Administration (NOAA) recorded sounds in the depths of the Pacific Ocean, the origin of which remains a mystery.


Scientists record and investigate noise oceans for over twenty years. They collected sound recording seismic activity, noise, movement of ice masses, sea animals. However, there are sounds, the origin of which has not yet been explained. Various theories were put forward, which included marine life, the instability of the ice cover, and even UFOs.

Sound, called "Roar"

NOAA experts have recorded this sound in 1997. Sounded at ultra-low frequencies, it was extremely powerful. His recorded in a remote area of the Pacific Ocean in the south-west of South America. By the nature of sound can be to suggest that it publish an animal. But none of the animals known to science could produce a sound that nature. Moreover, the volume of the "Roar" several times larger than any known noises that emit beings. "Roar" was simultaneously recorded several hydrophones, which were located at a distance of five thousand miles away from each other. And this makes it the most remote of all the recorded ocean sounds.

"Julia"

He was registered March 1, 1999. The sound lasted for about fifteen seconds. This noise was coming from the equatorial Pacific, where the source is located somewhere between South America and Easter Island. The sound volume "Julia" was also very high, it recorded a hydrophone, which divides the distance of five thousand miles.

Sound called "Slow"

This sound is recorded May 19, 1997. Its length reaches seven minutes. He was named a decelerating because the pitch is constantly decreasing. Beginning in 1997, the sound was repeated almost every year, and it was the location of its source just north of Easter Island, near the Pacific equator. Experts have hypothesized about the origin of "slow", but it was not confirmed. This sounds similar to the movement of the ice in Antarctica, but the location of the source says that there is no ice in places, so the question is still open.

"Train"

This sound is also recorded in the equatorial Pacific Ocean, just south of Easter Island. In its regular sound more volume and height to a fixed limit, like a train whistle.

The sound of "Lifting"

It was recorded in August 1991. This sound is made up of many repeating sound waves whose frequencies are rapidly rising. Following the discovery of the sound was recorded every year, but the volume and frequency steadily declined. And the seasonal pattern was found — the sounds of the highest frequencies were recorded in autumn and spring. The sound source is located to the north of Antarctica, somewhere between South America and New Zealand. According to the assumptions of scientists, this sound can be seismic nature, which is directly related to the volcanic activity in the region.

Sound, called "Whistle"

This sound is recorded July 7, 1997, and recorded his only one hydrophone. This is rather unusual because all other sounds caught at least four different sensor. In this case, the source of sound is in the equatorial Pacific Ocean, about 800 kilometers from Mexico City. Sound like a whistle, and the duration of up to one minute. Following the discovery of the whistle registered each year.

All these give rise to the mysterious sounds Pacific depth. You can build a lot of assumptions about their nature: seismic activity, marine animals, possibly a UFO. But there is good news — the answer can be quickly obtained. Currently, the development of new NOAA hydrophone sensors with increased sensitivity
